Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to a conveying device for slaughtering live pigs. Background Art

[0002] With the development of society and the gradual improvement of economic life, people's demand for food varieties is gradually increasing. Pork is one of the main categories of meat products. A large number of pigs are slaughtered and processed every day to meet the daily purchasing needs of citizens.

[0003] The prior art discloses some patent documents related to the field of conveying device technology. The Chinese invention patent with application number CN202310401753.2 discloses a pig conveying device for a pig slaughterhouse, including an installation mechanism, which places the pig on a holding plate. The pig's own weight drives the connecting rod of the holding plate to move downward. The holding plate moves downward, and through the rack transmission, drives the clamping plate to flip and clamp the pig. In this way, the pig can be clamped and fixed quickly, and the more violently the pig struggles, the greater the clamping force of the clamping plate. A limit rod with a wedge-shaped structure is provided on the movable plate, so that each time the connecting rod moves downward, the slots at different heights will engage with the wedge blocks on the limit rod. This can prevent the rebound of the holding plate, which in turn leads to a decrease in the clamping force of the clamping plate.

[0004] The existing technology usually clamps and fixes the pigs to restrict their movement for slaughter and bleeding. Restraining the pigs by clamping and fixing will increase the pigs' tension and cause them too much pain during the slaughtering process. The centralized setting of slaughtering equipment and fixing equipment will lead to a strong bloody smell, which aggravates the tension during the subsequent pig slaughtering.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Limiting the movement of pigs by lifting them up can also eliminate the tension caused by the binding. Then, by giving electric shocks to the pigs' heads, the pigs will instantly suffer from cardiocerebral paralysis and coma. The stunned pigs will then be transferred from the load-bearing pallet to the slaughtering and conveying mechanism through the unloading mechanism, and the pigs will be transported to a fixed slaughtering position for slaughter and bleeding.

[0018] 2. Through the threaded connection between the screw rod and the connecting strip, the corresponding connecting strip moves along the adjacent movable groove, and through the connection of the two limit stop strips, the connecting strip on the other side moves synchronously, and drives the two limit stop strips to move inside the placement frame, thereby reducing the accommodation space for the pigs and driving the pigs from the placement frame to the inside of the load-bearing frame.

[0019] 3. The contact ring on the surface of the fixed pin and the inner contact and rolling of the guide groove reduce the friction during the movement, so that the load-bearing plate moves up along the ascending section and moves to the parallel section, so that the load-bearing plate rises during the lateral movement and supports the pig's abdomen so that the pig's limbs are suspended in the air. During the rising process of the load-bearing plate, the head pad rises synchronously, so that the connecting pin on one side of the head pad moves vertically upward along the L-shaped guide rail, so that the arc groove on the top of the head pad supports the pig's head and rises synchronously.

[0020] 4. When the head pad rises to the highest point, the two head pads are in contact with the bottom of the limit plate, and the semicircular groove and the two arc grooves form a complete circle, thereby limiting the head of the pig and preventing the pig's head from moving when being electrocuted, resulting in incomplete stunning, thereby aggravating the pain of pig slaughtering.

[0021] 5. When the two load-bearing plates move away from each other, the two head pads move away from each other synchronously, and the connecting pin on one side of the head pad moves laterally along the top of the L-shaped guide rail. When the two load-bearing plates and the two head pads move away from each other and detach from the bottom of the stunned pigs, the pigs lose their support and fall downwards, and unloading is automatically completed.

DETAILED DESCRIPTION

[0031] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0032] like Figures 1 to 8 A pig conveying device for slaughtering shown in the figure comprises a placing frame 1 and a carrying frame 2, one end of the placing frame 1 is fixedly connected to one end of the carrying frame 2, and connecting bars 3 are arranged on both sides of the other end of the placing frame 1, and the adjacent sides of the two connecting bars 3 are hinged to the limit stop bars 4, and the adjacent ends of the two limit stop bars 4 are slidably inserted with the limit pin 5, and the connecting bar 3 is connected to the lateral displacement mechanism;

[0033] Two load-bearing plates 6 are arranged on the bottom surface inside the load-bearing frame 2, and two head pads 7 are arranged at one end inside the load-bearing frame 2. The tops of the adjacent sides of the two head pads 7 are provided with arc grooves 8, and the two arc grooves 8 form a complete semicircular shape. A matching linkage mechanism is connected between the load-bearing plates 6 and the head pads 7. A transverse driving mechanism is connected to the load-bearing frame 2, and the two head pads 7 are moved transversely by the action of the transverse driving mechanism, and the load-bearing plates 6 are moved synchronously with the head pads 7 under the action of the matching linkage mechanism, and move vertically upward during the transverse movement. A partition baffle 9 is arranged at one end of the load-bearing frame 2 close to the placement frame 1, and a vertical lifting mechanism is connected to the partition baffle 9;

[0034] The end of the supporting frame 2 away from the placing frame 1 is connected with a discharge mechanism and a slaughtering and conveying mechanism. The stunned pigs are discharged from the load-bearing support plate 6 by the discharge mechanism and are further conveyed by the slaughtering and conveying mechanism. During operation, the prior art usually clamps and fixes the pigs to restrict their movement for slaughtering and bleeding. The clamping and fixing of the pigs will greatly increase the tension of the pigs and cause excessive pain to the pigs during the slaughtering process. The centralized setting of the slaughtering equipment and the fixing equipment will lead to a strong bloody smell, which aggravates the tension during the subsequent slaughtering of the pigs.The present technical solution can solve the above problems, and the specific working method is as follows: by pulling out the limit pin 5 from the insertion place of the two limit stop bars 4, the limit effect on the adjacent end of the two limit stop bars 4 can be cancelled, and then the two limit stop bars 4 are rotated and opened along the hinged part with the connecting bar 3, and then a plurality of pigs for slaughter are driven into the inside of the placement frame 1, and then the limit pin 5 is re-inserted on one end of the two limit stop bars 4, so as to enclose the pigs in the placement frame 1, and then the two connecting bars 3 are synchronously moved toward the direction of the supporting frame 2 through the action of the lateral displacement mechanism, and the two connecting bars 3 drive the limit stop bars 4 to move. The pigs are moved and the space for accommodating pigs in the placing frame 1 is slowly shrunk. After the pigs are driven, one of the pigs is driven into the inside of the carrying frame 2 along the connection between the placing frame 1 and the carrying frame 2. The width of the carrying frame 2 can only accommodate one pig. The placement frame 1 is placed at an inclined transition position close to one end of the carrying frame 2 to transition the movement of the pigs. The pigs are moved closer to the carrying frame 2 through the inclined transition position during the gradual contraction of the accommodating space, so that the width of the pigs on both sides is reduced during the movement. The inclined transition position is used to prevent the pigs from being pushed and causing the tail to enter the carrying frame 2 first. When After the live pigs move to the inside of the load-bearing frame 2, the partition baffle 9 is moved downward to the inside of the load-bearing frame 2 through the action of the vertical lifting mechanism, so that the load-bearing frame 2 and the placement frame 1 are blocked and separated. After the live pigs are driven into the inside of the load-bearing frame 2, the heads of the live pigs are located in the arc groove 8 between the two head pads 7, and the two load-bearing support plates 6 are located under the abdomen of the live pigs. The two head pads 7 are moved along the direction of the load-bearing frame 2 away from the placement frame 1 through the action of the lateral driving mechanism, and the load-bearing support plates 6 are moved synchronously with the head pads 7 through the action of the coordinated linkage mechanism. The load-bearing support plates 6 rise vertically during the lateral movement and lift The pig's abdomen is suspended in the air, and the head pad 7 rises synchronously with the load-bearing support plate 6, and lifts the pig's head, so that the pig is suspended in the air, and then the pig's head is electroshocked to cause instant cardiocerebral paralysis and coma, and then the stunned pig is transferred from the load-bearing support plate 6 to the slaughtering and conveying mechanism through the unloading mechanism, and the pig is conveyed to a fixed slaughtering position for slaughtering and bleeding. By continuing to convey the stunned pig to the slaughtering area for slaughter, the panic caused by the on-site slaughter to the subsequent pigs can be reduced, and the pain caused by the pig being slaughtered can be reduced by supporting and stunning the pig, which is conducive to improving animal welfare. ;

[0035] As a further embodiment of the present invention, the lateral displacement mechanism includes two movable grooves 10 and four fixed plates 11. The two movable grooves 10 are respectively opened on both sides of the placement frame 1. The four fixed plates 11 are respectively fixedly connected to the two sides of the placement frame 1 and the two sides of the load-bearing frame 2 in pairs. A connecting rod 12 is fixedly connected between the two fixed plates 11 on the same side. One end of the connecting strip 3 extends along the adjacent movable groove 10 to the outside of the placement frame 1 and then slides and is inserted into the corresponding connecting rod 12. A screw rod 13 is rotatably connected between the two fixed plates 11 on one side, and the adjacent connecting strips 3 are threadedly connected to the screw rod 13. A first motor 14 is fixedly mounted on one of the fixed plates 11, and an output shaft of the first motor 14 is fixedly connected to one end of the screw rod 13; during operation, the screw rod 13 is driven to rotate by the output shaft of the first motor 14, and the corresponding connecting bar 3 is moved along the adjacent movable groove 10 through the threaded connection between the screw rod 13 and the connecting bar 3, and the connecting bar 3 on the other side is moved synchronously through the connection of the two limit stop bars 4, and the two limit stop bars 4 are driven to move inside the placement frame 1, thereby reducing the accommodation space for the live pigs and driving the live pigs from the placement frame 1 to the inside of the supporting frame 2.

[0036] As a further implementation scheme of the present invention, the vertical lifting mechanism includes a mounting frame 15, which is fixedly mounted on the top of the supporting frame 2. A first hydraulic cylinder 16 is fixedly mounted on the top of the mounting frame 15. The piston shaft of the first hydraulic cylinder 16 passes through the mounting frame 15 and extends to the inside of the supporting frame 2 and is fixedly connected to the top of the partition baffle 9. When working, the partition baffle 9 is driven by the piston shaft of the first hydraulic cylinder 16 to move vertically upward, so that the partition baffle 9 moves to the top of the supporting frame 2, thereby eliminating the obstruction at the connection between the supporting frame 2 and the placing frame 1. After driving one of the pigs into the inside of the supporting frame 2, the piston shaft of the first hydraulic cylinder 16 moves in the opposite direction and separates the connection between the supporting frame 2 and the placing frame 1 to prevent the pigs in the placing frame 1 from entering the supporting frame 2 when the pigs in the supporting frame 2 are transported.

[0037] As a further embodiment of the present invention, the lateral driving mechanism includes two slide rails 17 and two connecting pins 18, the two slide rails 17 are respectively fixedly connected to the two sides of the end of the supporting frame 2 away from the placing frame 1, and a movable bar 19 is slidably connected between the two slide rails 17. Second hydraulic cylinders 20 are fixedly installed on both sides of the supporting frame 2. The piston shafts of the two second hydraulic cylinders 20 are respectively fixedly connected to the two ends of the movable bar 19. The top of the movable bar 19 is fixedly connected to two L-shaped guide rails 21. The two connecting pins 18 are respectively fixedly connected to On the side of the two head pads 7 close to the movable bar 19, the connecting pins 18 are slidably limited inside the adjacent L-shaped guide rails 21; when working, the piston shafts of the two second hydraulic cylinders 20 move synchronously, driving the movable bar 19 to move laterally on the two slide rails 17, and in the process of moving the movable bar 19, the L-shaped guide rail 21 at the top of the movable bar 19 limits the connecting pin 18, so that the L-shaped guide rail 21 drives the adjacent connecting pin 18 to move, thereby causing the two head pads 7 to move laterally with the movable bar 19.

[0038] As a further implementation scheme of the present invention, the coordinated linkage mechanism includes two fixed blocks 22 and two guide grooves 23. The two fixed blocks 22 are respectively fixedly connected between the adjacent head pads 7 and the load-bearing support plates 6. The two guide grooves 23 are respectively opened on both sides of the load-bearing frame 2. The guide grooves 23 include an ascending section 2301 and a parallel section 2302. The end of the side of the load-bearing support plate 6 away from the head pad 7 is fixedly connected with a fixed pin 24. The fixed pin 24 is rotatably connected with a contact ring 25. The contact ring 25 is located inside one end of the adjacent ascending section 2301. During operation, when the head pad 7 moves laterally, the corresponding load-bearing support plate 6 is driven to move through the fixed block 22, and when the load-bearing support plate 6 moves laterally, the fixed block 22 drives the corresponding load-bearing support plate 6 to move. During the movement of the support plate 6, the fixing pin 24 on the side of the load-bearing support plate 6 moves along the guide groove 23, and rolls in contact with the contact ring 25 on the surface of the fixing pin 24 and the inside of the guide groove 23, thereby reducing the friction during the movement, so that the load-bearing support plate 6 moves up along the ascending section 2301 and moves to the parallel section 2302, so that the load-bearing support plate 6 rises during the lateral movement, and supports the abdomen of the pig so that the pig's limbs are suspended in the air. During the rising process of the load-bearing support plate 6, the head pad 7 rises synchronously, so that the connecting pin 18 on one side of the head pad 7 moves vertically upward along the L-shaped guide rail 21, so that the arc groove 8 on the top of the head pad 7 supports the head of the pig and rises synchronously.

[0039] As a further implementation scheme of the present invention, a limiting plate 26 is arranged above the two head pads 7, a semicircular groove 27 is provided at the bottom of the limiting plate 26, two fixing rods 28 are fixedly connected to one side of the limiting plate 26, and the bottom ends of the fixing rods 28 are respectively fixedly connected to the top of the adjacent L-shaped guide rails 21; during operation, when the arc-shaped groove 8 on the top of the head pad 7 supports the head of the pig and rises synchronously, the two head pads 7 move upward and approach the limiting plate 26, and when the head pad 7 rises to the highest point, the two head pads 7 contact the bottom of the limiting plate 26, and the semicircular groove 27 and the two arc-shaped grooves 8 form a complete circular shape, thereby limiting the head of the pig, preventing the pig's head from moving when being electrocuted, resulting in incomplete stunning, thereby reducing the pain of the pig during slaughter.

[0040] As a further embodiment of the present invention, the unloading mechanism includes two extension grooves 29 and two rectangular blocks 30. The two extension grooves 29 are fixedly connected to both sides of one end of the supporting frame 2. One end of the extension groove 29 is respectively connected to the adjacent guide groove 23. The extension groove 29 includes a conveying section 2901 and an unfolding section 2902. The two rectangular blocks 30 are respectively fixedly connected to adjacent fixed pins 24. Two spherical grooves 31 are provided on one side of the rectangular block 30 close to the supporting frame 2. Balls 32 are rollingly connected inside the spherical grooves 31. When working, when the fixed pin 24 moves along the ascending section 2301 to the parallel section 2302 and stuns the pig, the movable bar 19 continues to move through the action of the second hydraulic cylinder 20, and the fixed pin 24 moves along the parallel section 2302 to the extension groove 29, and moves along the conveying section 2901 of the extension groove 29 to the unfolding section 2902. When the rectangular block 30 fixedly connected to the fixing pin 24 moves along the unfolding section 2902, the ball 32 on one side of the rectangular block 30 contacts and rolls with the side of the unfolding section 2902, thereby reducing the friction during the movement. There is a certain distance between the rectangular block 30 and the conveying section 2901, so that when the two load-bearing pallets 6 move away from each other, the distance between the load-bearing pallet 6 and the rectangular block 30 will not get stuck when moving through the junction between the conveying section 2901 and the unfolding section 2902, ensuring that the load-bearing pallet 6 can be unfolded normally. When the two load-bearing pallets 6 move away from each other, the two head pads 7 move away from each other synchronously, and the connecting pin 18 on one side of the head pad 7 moves laterally along the top of the L-shaped guide rail 21. When the two load-bearing pallets 6 and the two head pads 7 move away from each other and detach from the bottom of the stunned pigs, the pigs that lose their support fall downwards and automatically complete the unloading.

[0041] As a further embodiment of the present invention, the slaughtering conveying mechanism includes a rectangular frame 33, which is arranged below one end of the supporting frame 2 away from the placing frame 1, and the interior of the rectangular frame 33 is rotatably connected to a plurality of rotating shafts 34, and the rotating shafts 34 are all fixedly connected to conveying rollers 35, and one end of the rotating shafts 34 is fixedly connected to a transmission gear 36, and one side of the rectangular frame 33 is rotatably connected to a plurality of matching gears 37, and the plurality of matching gears 37 are all located between two adjacent transmission gears 36 and meshed with the two adjacent transmission gears 36, and the other side of the rectangular frame 33 is fixedly installed with The second motor 38 has an output shaft fixedly connected to one end of one of the rotating shafts 34. When in operation, the output shaft of the second motor 38 drives one of the rotating shafts 34 to rotate, and the conveying rollers 35 on the rotating shafts 34 rotate synchronously, and are meshed with two adjacent transmission gears 36 through multiple matching gears 37, so that the multiple rotating shafts 34 rotate in the same direction. When the stunned pigs fall to the top of the rectangular frame 33 after unloading, the multiple conveying rollers 35 rotate in the same direction, and the pigs are moved and conveyed along the direction of rotation, and conveyed to a fixed position for slaughter and bleeding.

[0042] Working principle of the present invention:

[0043] By pulling out the limiting pin 5 from the insertion place of the two limiting stop bars 4, the limiting effect on the adjacent ends of the two limiting stop bars 4 can be cancelled, and then the two limiting stop bars 4 are rotated and opened along the hinges with the connecting bars 3, and then a plurality of live pigs for slaughter are driven into the interior of the placement frame 1, and then the limiting pin 5 is re-inserted on one end of the two limiting stop bars 4, so as to enclose the live pigs in the placement frame 1, and then the two connecting bars 3 are synchronously moved toward the direction of the supporting frame 2 through the action of the lateral displacement mechanism, and the two connecting bars 3 drive the limiting stop bars 4 to move, and make the space in the placement frame 1 that can accommodate live pigs full. The pigs are slowly contracted during the period of time. After being driven, one of the pigs is driven into the interior of the supporting frame 2 along the connection between the placing frame 1 and the supporting frame 2. The width of the supporting frame 2 can only accommodate one pig. The placement frame 1 is placed at an inclined transition position close to one end of the supporting frame 2 to transition the movement of the pigs. The pigs are allowed to move closer to the supporting frame 2 through the inclined transition position during the gradual contraction of the accommodating space, so that the width of the pigs on both sides is reduced during the movement. The inclined transition position is used to prevent the pigs from being pushed and causing the tail to enter the supporting frame 2 first. When the pigs move to the interior of the supporting frame 2, the pigs are moved to the supporting frame 2. After the pig is driven into the load-bearing frame 2, the partition baffle 9 is moved downward to the inside of the load-bearing frame 2 through the action of the vertical lifting mechanism, so that the load-bearing frame 2 and the placement frame 1 are blocked and separated. After the pig is driven into the load-bearing frame 2, the pig's head is located in the arc groove 8 between the two head pads 7, and the two load-bearing support plates 6 are located under the pig's abdomen. The two head pads 7 are moved along the load-bearing frame 2 away from the placement frame 1 through the action of the lateral driving mechanism, and the load-bearing support plates 6 are moved synchronously with the head pads 7 through the action of the coordinated linkage mechanism. The load-bearing support plates 6 rise vertically during the lateral movement and lift the pig's abdomen to make the pig move. The live pig is suspended in the air, and the head pad 7 rises synchronously with the load-bearing support plate 6, and lifts up the head of the live pig, so that the live pig is in a suspended state, and then the head of the live pig is electroshocked to cause instant cardiocerebral paralysis and coma, and then the stunned live pig is transferred from the load-bearing support plate 6 to the slaughtering and conveying mechanism through the unloading mechanism, and the live pig is conveyed to a fixed slaughtering position for slaughter and bleeding. By stunning the live pig and then continuing to convey it to the slaughtering area for slaughter, the panic caused by on-the-spot slaughter to subsequent live pigs can be reduced, and by supporting and stunning the live pig, the pain caused by the live pig being slaughtered can be reduced, which is beneficial to improving animal welfare.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may have various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention to be protected, and the scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
